Answer: 200 W
Explanation:
In physics, power is defined as the amount of work done divided by the time taken to do that work:
[tex]P=\frac{W}{t}[/tex]
where W is the work done and t is the time.
In this problem, the work done is W=600 J, while the time taken is t=3 s. Substituting into the formula, we find the power:
[tex]P=\frac{600 J}{3 s}=200 W[/tex]
